Description
Technical field
This utility model belongs to medical device technical field, specifically, relates to a kind of marrow puncture needle.
Background technology
Medullo-puncture needle, also referred to as marrow puncture needle, is a kind of puncture needle being used clinically for bone marrow extraction sample survey.The structure of clinical conventional all-metal marrow puncture needle can be divided into needle handle and needle body two parts, the long 55-65mm of needle handle at present, following part be sequentially connected with and form, including front power sheet, adjustable screw, fixing spiral, needle body cap and core needle cap totally five parts.The front end of needle body is needle point, and the rear end of needle body, through the centre bore of front power sheet, adjustable screw and fixing spiral, is fixedly connected on the centre bore of needle body cap.Front power sheet is an oval laminated structure, its major diameter 14mm, and minor axis 11mm, sheet thickness 1mm, front power sheet centre bore is positioned at the central authorities of ellipse and communicates with the centre bore of adjustable screw.Adjustable screw is the cylinder of diameter 6mm, total length 20mm, and its front end is fixing with front power sheet to be connected.The length of adjustable screw scalable needle body in rotary moving, namely regulates the degree of depth of puncture, and meanwhile the length of needle handle also has corresponding variation therewith.Fixing spiral is diameter 8mm, thickness is the lug of 3mm, and rotary fixing screw rotation also reaches fixation against adjustable screw.Needle body cap is " doing " type structure, total length 22mm, and its top and centre are oval, and oval major diameter is 11mm, and minor axis is 8mm.Marrow puncture needle needle body is hollow, and core needle is then enclosed within the cavity of needle body.The front end of core needle is the needle point that pointed and with needle body needle point collectively constitutes marrow puncture needle, and the rear end of core needle is fixing with nook closing member cap to be connected.Core needle cap is positioned at needle handle rear end, the fixing core needle by the connection with needle body cap.Core needle cap is " work " type structure, total length 12mm, and two ends are circle, is 8mm with the circular diameter of needle body cap link, and the circular diameter of the other end (i.e. needle handle end) is 11mm.
When puncturing, needle body is adjusted to certain length by turn adjustable screw and the fixing spiral of turn is fixed, by the point of puncture of tip alignment skeleton and withstand on front power sheet on finger with holding needle handle, suitably rotate and firmly puncture and reach desired depth, first pinch the nook closing member cap being positioned at needle handle rear end with hands and extract nook closing member, then connecting the centre bore bone marrow extraction sample of needle body cap with syringe.
Due to current clinical conventional all-metal marrow puncture needle needle handle more carefully, shorter, inconvenience is held and exerts oneself.And in the various piece of composition needle handle, adjustable screw, fixing spiral and three parts of core needle cap are all likely to occur activity when holding needle handle operation, and puncture all can be impacted by the activity of any part, especially the nook closing member cap of needle handle rear end it is positioned at, it is easy to be touched and cause that the displacement of core needle even comes off, causes failure or the pollution of puncture.
Summary of the invention
This utility model is in order to solve one of existing problems in above-mentioned prior art, it is provided that a kind of marrow puncture needle being prevented from the slip of nook closing member cap when carrying out bone marrow aspiration.
This utility model solves its technical problem and be the technical scheme is that
A kind of marrow puncture needle, including needle body and needle handle, it is provided with nook closing member in described needle body, described needle handle starts to be followed successively by front power sheet, adjustable screw, fixing spiral, needle body cap and nook closing member cap from needle body link, described nook closing member is connected with nook closing member cap, and described needle body cap and nook closing member cap abutting end are provided with at least 3 grooves, and the degree of depth of described groove deepens from needle body cap center gradually to periphery, described groove bosom is 1.2-2mm, and described nook closing member cap is provided with the projection of correspondence；Described needle body front end side wall is provided with circular hole.
This utility model also has following additional technical feature:
Preferably, described nook closing member cap side is provided with the anti-slip veins of vertical direction.
Preferably, described nook closing member crown end is circular arc.
Preferably, the material of described marrow puncture needle is metal.
Beneficial effect: this utility model is provided with at least 3 grooves at needle body cap and nook closing member cap joint, and groove is set to the short shape in periphery deep centre to be prevented effectively from and be touched the problem causing nook closing member to dislocate when carrying out bone marrow aspiration owing to firmly excessive or piercing process running into nook closing member cap when hard place needs to rotate marrow puncture needle, effectively prevent trouble and worry when medical worker punctures, and, more effective in the correctness and firmly more convenient punctured, alleviate patient's misery；Nook closing member crown end is that circular arc is easy to hold, and conveniently firmly, alleviates medical worker's workload.
Additional aspect of the present utility model and advantage will part provide in the following description, and part will become apparent from the description below, or is recognized by practice of the present utility model.
